tableland

The northwestern tableland area has a continental plateau climate with long and chilly winter and cool humid summer.

西北高原地区是大陆高原气候，有漫长而寒冷的冬季，凉爽而湿润的夏季。

Few of tropical Africa's rivers are navigable from the ocean, dropping as they do from interior tableland to coastal plains by a series of falls and rapids.

酷热的非洲，几乎没有适于航海的河流，这些河流从内陆高原到海岸平原一路穿瀑布、过险滩，倾流而下。
